The IQ-650 Element is the first of TUSA's new range of computers to be introduced in 2009. The Element is an easy-to-use, single button, puck-style computer offering a myriad of dive data details plus some new features including a Deep Stop function all in an affordable package.  The Element is available in a wrist or console version.  

Deep Stop Function
Several TUSA computers feature a deep stop function for additional safety. The deep stop mode is activated when a dive exceeds 80 FT (24M) for more than 1 second. Upon ascent, the computer will display a Deep Safety Stop screen and the recommended stop depth for a period of 2 minutes.  This deep stop is highly recommended as additional opportunity to off-gas, but is not mandatory. If the diver chooses not to serve the stop it will not adversely affect the remaining No-Decompression Limits of the dive.
